Professional Experience
Leah Keller is a certified personal trainer and the founder of Every Mother (formerly The Dia Method), a fitness system endorsed by medical and birth professionals worldwide. With over two decades of fitness experience, Leah empowers and equips women to exercise safely during pregnancy, labor with confidence, and restore core strength and total body fitness after birth – no matter how long it’s been. The EMbody Program grew out of her private training practice in New York City. It earned unparalleled medical validation when researchers at Weill Cornell Medical School collaborated with Leah to conduct a pilot study with 63 women, all of whom achieved full resolution of diastasis recti in less than 12 weeks. Leah is now collaborating with researchers at the Hospital for Special Surgery, Weill Cornell, and Harvard Medical School to conduct a randomized, controlled clinical trial to gather additional data on the health benefits of the EMbody core strengthening program. Leah holds an MA in English, a BA in Psychology, and has been featured as a women’s health expert by major media outlets, including NPR and Good Morning America. She has a young daughter and a baby boy.
